ADJUSTMENT
Follow the Adjustment Steps below
for proper testing of the Safety
Reverse System.
1. The opener must reverse if the door comes in
contact with an obstruction. A closing door should
reverse with little effort, and open completely.
Refer to Adjustment Step 2 in Owners Manual
for instructions.
2. At completion of installation of opener and testing
of reversing feature in #1 above, the 1 inch
reversal test must be completed. (Use 2x4 board
laid flat against the wall or door edge.)
• On a sliding door door, place a 2x4 board
between the door and wall of a closing door.
Door must reverse on the board and open
completely. Repeat at opposite wall if two
openers are installed.
• On a swing out door, insert a 2x4 board between
the closing door sections. Door sections must
reverse and swing open completely.
• If the door stops on the obstruction, it is not
traveling far enough in the closing direction.
Increase the DOWN limit adjustment screw
counterclockwise 1/4 turn. Repeat test.
• When the door reverses on a 2x4 board, remove
the obstruction and run the opener through
complete travel cycle to test adjustment.
• If the door will not reverse after repeated
adjustment attempts, call for trained door
systems technician.
IMPORTANT SAFETY CHECK
Repeat Adjustment Steps in Owners Manual
after:
• Each adjustment of door arm length, force controls
or limit controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.
• Too much force on garage door will interfere with
proper operation of safety reversal system.
• NEVER increase force beyond minimum amount
required to close garage door.
• NEVER use force adjustments to compensate for a
binding or sticking garage door.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with one-inch high object (or 2x4 laid flat)
on floor.
